To all whom it may concern:

Be it known that HERBERT M. HAINL NE, a citizen of the United States of America, residing at Sciota, in the county of Mo- Donough and State of Illinois, has invented new and useful Improvements in Combination Locks, of which the following is a speclfication. D

The, object of the invention is to provide a simple, relatively inexpensive and efiicient combination lock adapted for general purposes but designed especially for use in securing a -motor meter in place against surreptitious or accidental displacement or removal, such motor meter as in the ordinary practice being carried by the cap of an automobile radiator and being subject to displacement by the vibration of the vehicle and of misplacementand loss by neglect to return the same to its proper position after removal for the introduction of water into.

the radiator system; and with this objectin view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1 ,'s an elevation partly broken away of a lock mechanism embodying the invention applied to a motor meter.

Figure 2 is a sectional view of the sametaken on the plane at right angles to that of Figure 1.

Figures 3, 4 and 5 are transverse sectional views taken respectively on the planes indicated bythe lines 33, 44 and 55 of Fi re 2.

*igure 6 is a plan view of'the hearing or assembling sleeve or thimble.

Figures 7 and 8 are side views in detail respectively of the bearing or assembling sleeve and the core.

-Figure 9 is a detail view of the locking P The lock consists essentially of a plurality of revoluble tumbler disks 10 between which are arranged spacing disks 11 held .in assembled relation by a terminally flanged Figure 10 is a detail view in section of a; modified construction of core having the thimble or sleeve 12 and all arranged in a Specification of Letters Patent, P t t June 20, 1922 I Application filed October 27, 1921. Serial No. 610,718;

ing as to permit of access to the peripheries v of the disks from the open inner side of the casing to adjust the disks rotatably in the operation of the lock. The disksare v peripherallymotched as indicated and the sleeve or thimble is provided with radial lugs 15 engaging suitable notches 16 in the inner peripheries of the spacing disks-3 A core 17 is carried by the stem" 18 of the mo-' v tor meter 19, said stem'being the. element which in the use of the device performs the function of a bolt of which the position controls the movement of a latch pin 20 which must be displaced after proper ad justment ofthe. locking mechanism in order to perm1t of'the disengagement of the latch pin and the removal of the plug from the -machine.'

In the construction illustrated the latch pin is provided with reduced neck portions 21 adapted for engagement with keyholeslots 22 in a barrel 23v which constitutes the stopper tofit in the filling opening of a radiator tank, and the'normal position. of the stem or bolt 18 with relation to the bar-.

rel 23 is such as to obstruct the movement of the latch pin and prevent its registration with the enlarged portions of the keyhole slots and therefore prevent its disengagement from the barrel. The latch pin is adapted for engagement with the'terminal link of a retaining chain 24 which, by extending into and being anchored within the tank serves to permanently connect the lock mechanism and the motor meter carried thereby to the tank although permittin of the removal of the barrel from the fil ingopening sufliciently to enable the tank to be supplied.v In order to-= disconnect the motor meter from the machine it is neces-- sary to manipulate the lock and withdraw the stem or bolt 18 sufliciently to permit of the registration of the latch pin 20 with the enlarged portions of the keyhole slots in the barrel. g g

'In the construction illustrated the stem or bolt 18 is. threaded into engagement with the core 17 and the engagement is of a sufliciently rigid character to prevent displacev ment of the former from the latter, and car- 4 ried by the core is a series of lugs 25' extending through a slot 26 in the sleeve or din'al movement of the stem or bolt 18 andthe core carried thereby is prevented by the engagementof said lugs 25 with theunder surfaces of the tumbler disks; whereas by a proper adjustment of the tumbler disks to register the notches 27 thereof with the lugs 25 a longitudinal or axial movement of the V ranged during the unlocked condition of the device to remove the notches 27 thereof from core is-permitted suflicient to withdraw the inner end of the stem or bolt from the path of movement of the latch pin to allow of .the disengagement of the latter from the barrel.

In the construction illustrated the outer peripheries of the tumbler disks are notched to provide finger holds so that they may be roperly manipulated.

n the modified construction illustrated in Figures 10 to 12 inclusive the hi or teeth 25 on the core 17 are yieldingly mounted by means of a plate 25 held in place by a spring 25, and the spacing d1 sks 11 are flanged as shown at 11 to provide clearance so that after the bolt or stem has been withdrawn it may be returned to lgcking position after a readjustment of the tumbler disks should they have become disartheir position in registration with the lugs of the core.

Moreover in the construction illustrated it will be noted that the barrel 23 is provided with an inwardly -flanged upper end as shown at 27 for engagement with the lowerfiange 28 of the sleeve or thimble 12.

Whereas it is preferable as illustratedin the drawing to provide the upper end of the barrel 23 with an inturned flange, it will be understood that the mechanism is susceptible of a modification in this respect to the extent of making the same either fast or se arate.

urthermore it should be noted that the look as described can not be removed' with a wrench or otherwise until the parts are separated as the barrel and tumbler disks turn freely around the assembling sleeve and core and can not be unscrewed until these parts are takenofi'.

Having described the invention, what is claimed as new and useful is -1. A combination lock having an axially movable stem or bolt andassociated tumbler disks for locking the same against axial movement, .and a sleeve by which said disks metricall hea set-i mounted and which has an interlocking engagement with the spacing disks, and an axlally movable stem or bolt'having a core fitted in said sleeve or thimble and provided with radial lugs projecting through a slot in the sleeve or thimble for passage through notches formed in the inner peripheries of the tumbler disks, in combination with a barrel having opposite keyhole slots and a latch pin fitted in said slots, said stem or bolt being normally arranged in the path of movement of the pin in the slots.

3. A combination lock having a plurality of revoluble tumbler disks and inter osed spacing disks, a terminally flanged thimble or sleeve upon which the tumbler disks are mounted and which has an interlocking en gagement with the spacing disks, and an axially movable stem .or bolt having a core fitted in said sleeve or thimbleand provided with radial lugs projecting through .a'. slot in the sleeve or thimble for passage through notches formed in the inner peripheries of the tumbler disks, said stem or bolt carrying a motor meter and having a threaded engagement with said core.

4. A combination lock having a plurality of revoluble tumbler disks and interposed spacing disks, a terminally flanged thimble or sleeve upon which the tumbler disks are mounted and which has an interlocking engagement with the spacing disks, and an axially movable stem or bolt having a' core 'fitted in said sleeve orthimble and provided with radial lugs projecting through a slot in the sleeve or thimble for passage through notches foi'med in the inner peripheries of the tumbler disks, a caslng bemg arranged in enclosing relation ture.
